RC2 started off working fine but encountered too many force close issues and sudden reboots. I had wiped/cache like 4 times prior to flashing. Did it again, after someone suggested it and still had problems. So went back to UD 2.5 for now.

Anything you want to use on home screen like app with widgets or live wallpaper need to be internal. Otherwise you will either not be able to access the widget or upon reboot the widget and wallpaper are gone. Also this can occur if you are using a lot of memory with the apps running and the home can't hold the sd items in place.
